Hello. How many pieces in your model? What is your computer spec, operating system, browser, etc?

One of them has 42, other has 104. Its a laptop, Intel Core Duo CPU, T6500 2.1Ghz, RAM 2 GB. But its 10 years old, had several virus.

I have the same problem, though rotating the view seems unaffected. My model has 902 pieces, relatively new laptop, It's a Windows 10.

Which browser do you use? This is definitely not normal. 1000 pieces is nothing on a computer and you shall not really see any slow down.
Chrome and Safari are the fastest to build but Firefox is able to export quicker.

Now i'm using firefox, the problem over!

I’ve also tried using Firefox on my desktop computer, but it’s still slightly faster compared to when I use Mecabricks on Microsoft Edge and Google Chrome.

Mecabricks wont open of firefox, and is too slow on any other browser, what should I do?

Alright, I’m using the recommended settings for Mecabricks to run smoother and faster, but the Workshop is now at the slowest speed. Is there a problem with this?

im having the same porblem. its slow when i orbit around and when i move things around

If you use a laptop with an integrated and a dedicated GPU under Windows, you shall make sure that you browser runs with the dedicated GPU. For some weird reason it is not the default setting. You shall set it in your graphic card panel (nvidia or others).

Weird. My Chrome is slower than Edge or Firefox.

My default browser is Microsoft Edge.

Same

The slowdown also happens to me because whenever I place a block or try to edit it, it either glitches or lags my whole computer or mecabricks crashes or everything stops loading in. My browser is Google, and just now i tried edge it worked for a bit then started to get laggy again after I left it for like 10 minutes it stopped getting laggy but then when i continued to go it started lagging again. but anyways the best my laptop can go to is too much lag and loading problems with some broken blocks that make my screen load for 10 minutes and dont let me delete them etc. dont mind my grammar i know its bad and same with my spelling

Try another browser, or clear cache. Google Chrome isn't nearly fast as Edge on my computer, possibly because I rarely used Edge until now.

Hi. It slows down as I add more pieces. I'm making a house, and it's slowing down to the point that I can't even move or colour objects! Why does this happen?

Obviously it slows down as you add more objects, as there is more data needed to load each individual brick. May I ask how many parts your house has?
